The UTXO pool may be housed in local memory or as an indexed database table on persistent storage. In response to a getdata message from the node, peers will send a merkleblock message that contains only block headers for blocks matching the filter and a merkle path for each matching transaction.

To add a pattern to the bloom filter, the pattern is hashed GALA by each hash function in turn. Applying the first hash function to the input results in a number between 1 and N. The corresponding bit in the array is found and set to 1, thereby recording the output of the hash function.
